Robot surprises by revealing the function of feathers in dinosaurs; see video

As technology and paleontological studies advance, humanity discovers new facts about the dinosaurs.

For a long time, it was believed that these animals were related to reptiles, but now we know that they are actually closer to birds.

In fact, several species of dinosaurs had feathers and wings, even though they were not 100% functional and did not allow flight.

In this way, the real usefulness of feathers was questioned: after all, why did animals have them if they couldn’t use them to take off or at least glide?

Recently, a dinosaur robot built by researchers was able to answer such questions in an unprecedented way. With the machine, researchers discovered why there were feathers on dinosaurs.

How did the robot experiment occur?

To date, several theories have been developed to try to justify the existence of feathers and wings on the bodies of dinosaurs, but none of them have solved the enigma in a satisfactory way. Did they give more speed? Did they protect from the cold? Were they useful for mating?

The answer was only obtained by a robot of metal called ‘Robpteryx’, a mechanized version of a prehistoric specimen called ‘Caudipteryx’, which was the size of a modern peacock, with feather-covered protowings and tail.

The animal lived 124 million years ago in an extremely hostile environment full of dangers.

Thus, scientists were able to test a hypothesis suggested by South Korean scholars, called the ‘flush-pursue strategy’.

According to her, the animals would use their wings to scare prey from their holes and capture them. Remembering that this strategy has already been observed in modern birds.

Therefore, with this information, the experiment carried out three demonstrations of how the aforementioned body structures could be used:

  • The machine expands the forelimbs with the protowings and makes the grasshopper jump/fly, indicating that it could indeed escape from a hiding place;

  • The robot folds its forelimbs with its protowings and, again, the insect jumps/flies to distance itself;

  • The mechanism makes upward movements with the feathered tail and the grasshopper flies away.

According to the results, the project’s lead author, Jinseok Park, from Seoul National University, reveals that the grasshoppers jumped more frequently when the robotic replica showed its wings. wings.

Furthermore, they jumped more when these parts were painted with black and white spots.

According to Piotr G. Jablonski, another member involved in the research, this could be a strong indication that the evolution of dinosaurs and their feathers was partially shaped by insect neurons, which were, in this case, the main source of food for ancient animals. .
